Drainage solutions for water-logged properties. Whether it’s a standalone project or integrated into a larger job, property drainage is an important, yet often overlooked aspect affecting most, if not all, properties. With all the new construction taking place, topography is constantly being altered. This affects not only the property under construction, but usually has secondary consequences—including runoff and drainage issues—for surrounding properties as well. Effective stormwater drainage systems either facilitate water flow to lower elevations or allow for corrective grading. Since each property is unique, I first perform a property evaluation to examine its available elevation, soil conditions, typical influx of water volume, and traffic. These factors affect the depth, diameter, thickness, and composition of the pipe that can be utilized. They also affect the type of soil separator and gravel that can be used. Described below are details on several different property drainage solutions. I’ve also included a simple calculation used to determine the gallon capacity when estimating construction of a dry well. Property Drainage Systems Does the property have soggy areas or pooling during or after rains? These are typically the most common problems encountered. Poor drainage areas that result in these issues are typically best resolved by installing plastic drain boxes, cap surface drains, or larger capacity concrete catch basins with lift-off iron frame and grate. Appropriately sized underground drainage lines, usually PVC, are also installed, and connected to drain boxes or surface drains. These lines allow water to run downhill to a lower elevation.
